Direct ink writing opens the door to complex-shaped objects with isotropic structural color

Structural color is a more durable and less hazardous alternative to conventional pigments, but the angle-dependence of the color limits its broader application in synthetic systems. Researchers at ETH Zurich proposed a 3D printing process to create complex-shaped objects with angle-independent “isotropic” structural color generated from photonic colloidal glasses.

Pottery probe shows continuity of southeastern Hispaniola cultures

Mona Passage, a strait which separates the islands of Hispaniola and Puerto Rico, is believed to have served as a reception area for migration groups during the early Common Era. A recent open-access study contends that despite there being a broader regional network of interaction, the stable manufacturing tradition suggests a cultural continuity in the communities that lived there.

M7C3: Unveiling the structure of a misunderstood carbide

The use of data-driven methods to tailor the growth characteristics, stability, and mechanical properties of M7C3-type carbides is hindered by ambiguity surrounding the carbide’s structure. To overcome this uncertainty, researchers from the United States and Israel used a variety of imaging techniques to reveal the atomistic structure of M7C3 carbides.
